Specification of Letters Patent.

PatentedSept.16,1913.

To all wlwm it may concern:

Beit known that I, SAMUEL McKinnor, a citizen of the United States, residing at Cleveland,in the county ofCuyahoga and State of Ohio, have invented a certain new and useful Improvement 1n Grease- Gups, of which the following is a full, clear, and exact description.

This invention relates to a which is intended for the dispensing of heavy greases which are normally of such consistency that they do not flow. Greases of this character are insome respects better lubricants than oil, and they have the added advantage that they are cheaper. In utilizing greases of this character as lubricants, the usual method is to employ a rod of copper or other good conducting material which bears upon the shaft and extends into the grease cup, the heat of friction between the rod and the shaft furnishing suflicient heat to melt portions of grease adjacent the rod which will flow along the rod. to the bearing.

In the forms of cups with which I am familiar, there have in many of them been grease cup .110 means for controlling the flow of the lubricant after it has become heated, so that frequently excess of lubricant have been ap plied to the shaft resulting in waste of lubricant, and further, it is quite undesirable that the lubricant escape and drop from the bearmgs.

Some forms of grease cupin which regulation has been attempted have failed to make the regulation effectual forvarious reasons, 7

It isthe object of this inventionto provide a grease cup of the type heretofore described in which the regulation offlow of the grease along the rod from the cup shall be positively and certainly regulated, and further providing-a positive shut-01f of the fiow of grease when this may be desirable.

Generally speaking, the invention comprises the elements and combinations thereofset forth in the accompanying claims.

Reference should be-had to the accompanying drawings forming a part of this specification, inwhich Figure 1 is a vertlcal elevation,partly in section," of the grease cup;.Fig. 2 is a section along the line 22 of Fig. 2, with certain portionsfurthersectioned to show the valve construction 3 shows in plan the features' of construction of the valve; and Fig 4: shows in plan the movable portion of the valve.

The cup or container portion 1 is of usual shape, and may be made of any desired size. Thls cup 1s provided with a depending portion 2, a portion ofwhich is threaded and which is adapted to besecured upon a bearlng which is-provided'with a threaded opening to receive it. t

Theupper part of the depending portion 2 1s usually formed. with sides or faces in order that a wrench may be applied thereto to turn the cup. v

The cup is preferably made by drawing from a tube of metal, in which event the portion 2 .will be separately formed and welded to the cup blank, or if desired, the whole cup and the depending portion 2 may be drawn with a single operation.

The cup is provided with a cover 3 which is secured upon the cup 1 in any desired manner, and for the purpose I have shown a bayonet joint as indicated at 1.

WVithin the cup there is placed a partition or-disk5, this disk being of substantially the same diameter as the interior of the cup and lies upon shoulders which are formed upon the interior wall of the cup. Lying upon this disk is a second disk 6 which is of the form shown in Fig. 3. That is to say, there is a substantially circular portion re moved from this disk, the center of the circular portion removed being non-coincident with the center ofthe disk 6. This disk is placed upon the disk 5 in such manner that the opening in the edge of the disk, formed by the circular portion removed, will lie substantially coincident with a slot 7- which is formed in the side of the cup 1. The slot,

as will be noted, is of slightly less length than the opening in the disk 6, this being for the purpose of giving the movable portion of the'valve plenty of room for movement; i

Cooperating with the disk6 is a member 8, which is of theform shown in Fig. 4, the

larger circular part fittingwithin the opening in the disk 6,*whilethe portion 8 of this member. extends throughthe slot 7 to the exterior of thecup, so that movement may-be imparted to the disk 8 when desired.

-' Above the disk 6 and the disk 8 is a disk 9. -This disk issimilar to the disk 5 and is made to have a drivingfit with the side wall of the cup. then therefore, it is placed through the said movable member, and

through the support, through which the aforesaid rod extends, the movement of the movable member of the valve serving to vary the size of the opening in the valve mechansm through which the rod extends.

6. In a grease cup, the combination with a container havin an outlet, aheat conducting rod extending through said outlet into the container, a valve mechanismwithin the container, saidvalve mechanism being provided with an opening through which the rod extends, said valve mechanism being provided with a movable portion having a slotted opening, the slot being of substantially the diameter of the rod, and means extending upon the outside of the container for moving said movable member.

7. In a grease cup, the combination with a container having an outlet, a heat conducting rod extending through the outlet into the container, a valve mechanism with in the/cup, said valve mechanism comprising a disk adapted to be supported in the cup, a superimposed disk provided with an opening, a movable valve member adapted to cooperate with the last mentioned disk and guided by the walls of the opening therein, the said movable valve portion being of slightly less thickness than the thickness of the superimposed disk, and a holding disk adapted to have a driving fit with the walls of the container, said disk engaging the superimposed disk, whereby the super imposed disk is firmly held between the disks upon the opposite sides thereof, and means extending upon the outsides of the container for moving the movable member of the valve,

In testimony whereof, I hereunto aflix my signature in the presence of two witnesses.
